Velleman Earth Listener I2C error

Hi! I got my dad an earth listener, and after making sure all the connections are in place on startup the display shows:

CCS811 status: I2C_ERROR
AS3935 status: NOT FOUND
BME280 status: NOT FOUND
SD card: NOT FOUND

None of the sensors also report the correct data. The product also had some cracks on the display straight out of the box. Could it be that the product is broken?

Any help is very much appreciated.

Hi poor,

Is it possible to upload clear (hi res) photo’s of your connections from sensor?
Maybe a wrong connection. make sure both jumper mus be disconnected.

*Make Sure SDA of sensor boards are connected to SDA of mega sensor shield *
and SCL of sensor boards to SCL of mega sensor shield, for i2c bus connection.

Best regards,
Velleman Technical Support

Hi Support,

I got the same issue and checked cable several times.

[ Startup ]
CCS811 status: I2C_ERROR
AS3935 status: DEDECTED
BME280 status: DEDECTED
SD card: DEDECTED

[ Running ]
18:54:11.025 → Failed to get ERROR_ID register.
18:54:14.646 → Error with CCS811 sensor!

I also tried another CCS811 (CCS811only) sensor and got the same error.
So, I think not, it’s a defect on VMA342 board.

Other tests:

Any Idea?

Thanks and BR,
